SKATE.

Application led January 16', 1.826. Serial No, 81,635.

This invention relates to skates, and has for its object to provide animproved skate which when used will be very agreeable to the user andwill enable the various shocks to which skates are subjected, to bereadily absorbed by a mechanism provided in the skate so that suchshocks are not transferred to the user of the skate. More particularly,the object of the invention is to provide a very simple `structure whichcan be readily manufactured at a small expense and simplicity` ofmanufacturing machinery,

' For the fullillment of these objects the invention consistsessentially of a skate frame having shock absorbing chambers therein inwhich the shock absorbing mechanism is provided. These chambers arepreferably made of one piece with the frame of the skate whereby asimple means is provided which can be readily manufactured.

The invention, in an embodiment thereof, will be described hereinafter,shown in the drawings, and finally pointed out in the claims. In theaccompanying drawings,

Figure 1 is a side view {particularly in longitudinal section of myimproved skate;

Fig. 2 is a plan view of the frame of my improved skate;

Fig. 3 is a vertical transverse section taken on line 3-3 of Fig. 1; andY Fig. 4 is a horizontal section taken on line 4-4 of Fig. 1.

' Similar characters of reference indicate corresponding partsthroughout the various views.

Referring to the drawings, and more particularly to Fig. 2, my improvedframe consists essentially of two parts, a rearward part and a forwardpart. The rearward part indicated by portion has a chambered portion 11,with a bottom of substantially circular shape, and this chamberedportion extends at the rear of the rearward portion 10, upwardly toframe the counter of the skate frame and has a configurationsubstantially that of the counter of the shoe of the user. This counterportion 12 is made of one piece with the chambered portion 11, so thatthe entire rearwardportion of the skate frame may be struck out bysuitable manufacturing machinery, as one piece. The rearward portion 1-0is provided with an opening 13 through which a bolt 14 passes, which hasa nut 15 on the screw frame may be adapted to be used with lshoes ofdifferent sizes.` The rear-most portion of the rearward portion 10 isprovided with suitable means as screws 18` which secure straps 19thereto as shown in Fig. 1, and a suitable strap 20 is applied by anysuitable means to the counter portion 12, in order to surround the ankleof the user. The rearward portion 10` is further provided with anopening 21 through which a nozzle portion 22 ofa pneumatic shockabsorbing .device passes This nozzle 22 `is provided with a Vsuitable,valve Vof any well-known construction, indicated by 23. The pneumaticshock absorbing device consists'essentially of a rubber sphere indicatedby 2 4 and which has a configuration substantially that of theconfiguration of the chambered portion 11, whereby this sphericalportion 24 is slated within the chambered portion 11. The singlepneumatic portion 24 is in the nature of Va balloon. The chamberedportion above the pneumatic shock ab;- sorber 24 remains free and openfor the entrance therein of the heel of the shoe.

The forward portion of the frame is also provided with a chamberedportion partially of straight lwalls with a 'circular bottomY 31./Vithin the chambered portion 30 at the upper part thereof, a solidblock of rubber of circular shape indicated by 32 is provided, uponwhichthe forward portion of the shoe rests. y A y This block of rubber32 in turn, rests upon a metallic disk or plate 33 having at its centralportion a cylindrical tubular member 34, in which seats a piston member35 havingV a seat portion 36 resting upon the bottom 31 of the chamberedportion 30. The tubular member 34 is provided with interior screwthreads and the piston member 35 is provided with eXterior `screwthreads. By the members 34 and 35 being adjusted in respect to eachother the adjustment of the block of rubber 32 is brought about so as tohave this block 32 in the proper'position. The resiliency of the forwardpart of the shoe is ob tained as a result of the resiliency of the blockof rubber 32. The forward portion 17 if. D

is provided with depending members il? and a screw bolt 38 adapted to beengaged by the usual key which operates in the well known side ianges39, in order to grip the sole of the shoe to the forward part of the'skate.

By the arrangement of the parts as has been described, the heel'portionof a user is resiliently sustained in position by the shock absorbingdevice, so that this most sensitive part of the user is not subj ectcdto the continual shocks which the roller skater is usually subjected to.rlihe rubber resilient block 32 takes up the vibrations at he forwardend of the: foot of the user. This rubber resilient member' 32 beingarranged in proximity to theball of the foot. Both the chambered portionll and the chambered portion 3G haveralso downwardly extending ianges Oand dlrespectively, through which the shafts il@ of the wheels 43' pass.

'lhus it will be seen that the portions of the skate with theirchambered portions and the shaft journaled portions are of one piece,which can be readily struck out by machinery and made at a very lowexpense. rlhey may be readily assembled and by the insertion of theshook absorbing device, a skate is provided which'is resilient in useand agreeable to the user.

My improvements as l have described them are shown as applied to aroller skate, the wheels being suitably arranged in the well knownmanner to the shafts i5 But the structure as described may be readilyapplied to ice skates, by simply having the shafts pass through the iceblades and by a suitable lock device the saidV blades may be fastened tothe shafts. The ice blades are inl .serted between the depending flangesd() and al, and suitable nuts are provided to hold the ice bladesreadily in position.

I have shown an embodiment of my invention but it is clear that changesmay be made therein without departing from the spirit of the same asdefined in the appended claims.

l claim as new:

l. A skate comprisingy a frame consisting vof forward and rearwardportions adjustably oined, said portions having chambered Lacasse partstherein, and a pneumatic shock absorb device in one of saidchamberedparts.

2. fr skate comprising a skate frame consisting of two parts, each parthaving a chambered portion, a pneumatic shock absorbing device in onechambered portion, and an adjustable cushion shock absorbing device inthe other portion.

3. A skate comprising a skate frame consisting of two portions, eachportion having a chambered portion, a shock absorbing cevice in .eachchambered portion, and means for joining said two portions adjustablytogether, a counter portion on one of said chambered portions integrallytherewith, and shaft supporting members integral Vwith ach chambercdportion.

A `skate comprising a skateV frame formed of two parte, a rear part anda forward part, the said rear part having a chambered portion with acounter portion extending upwardly therefrom and a shaft supportingportion extending below theV same, Y*said chambered portion having aspherical pneumatic member therein with means for maintaining`resiliency, said means extending through the chainbered portion, andsaid rearward portion having also .suitable straps, said forward portionhaving a chambered portion, an adjustable member in the chamberedportion, a resilient rubber block on said adjustable portion, shaftsupporting members on said chai ibered portion, and clamping means onsaid forward portion, and means joining the forward and rearwardportions adjustably together.

5. fr skate construction comprising a skate frame having chamberedportions in its rear and forward portions, a pneumatic shock absorbingdevice in the chambered rear portion for receiving directly the heel ofthe wearers shoe, and a shock absorbing device in the forward chamberdirectly exposed to the sole of the shoe and adjustable toward and fromsaid shoe.

ln testimony that l claim the foregoing as my invention, l have signedmy name hereto.
